Open Evaporative Towers use ambient air and evaporation to cool process water and are the least expensive to purchase. Scales can design, supply, install and start-up your cooling tower system, which are available in many configurations to meet specific operating requirements.
Closed Loop Cooling Towers circulate the warm process fluid from the heat source to the coil of the closed circuit cooler. The fluid in the coil transfers its heat through the coil tube walls in a sensible exchange to the spray water that floods over the tubes. Just as important, closed-loop systems completely isolate process water from the tower water, protecting process equipment from contamination. This design, along with corrosion inhibitors in a glycol process mix, can help to eliminate scale in equipment and piping.
